Claims.

My invention relates to an improved shade construction, and particularlyto a novel construction and arrangement of frame, the covering material,and to an improved means for securing the said covering material to theframe.

The invention has among its objects the production of a shade of thekind described which is not only particularly attractive, but which maybe conveniently, economically and satisfactorily manufactured.

A further object of the invention is to provide a new and novel frameconstruction which may be pre-built and to which the covering materialmay be readily, conveniently and durably secured.

A further object is theproduction of a shade of the kind described inwhich thescovering material is made in the form of a seamless tube ofknit or woven or elastic or semi-elastic material which may be readilystretched in position on the frame and in which the material, due to itsnature, after stretching in applying, willremain tautand smooth withoutwrinkles,

A further object is the production of a frame provided with means forreadily attaching the cover to the frame by means of one or more annularmembers which may be sprung into position and positively engaged intheframe.

Many other objects and advantagesof the construction hereinshownanddescribed-willbe obvious to those skilled in the art from thedisclosure herein given.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claims.

In the drawing, wherein like reference characters indicate like orcorresponding parts:

Fig. I is an elevational view of a lamp shade structure embodyingfeatures of the invention, a portion of the shade construction beingbroken away to better illustrate the construction;

Fig. 2 is a perspective view of the shadeframe with the cover removed;

Fig. 3 is a sectional view taken substantially on line 3-3 of Fig. l; d

Fig. 4 is an enlarged perspective view showing the details of one of themethods ofattaching the shade to the frame;

Fig. 5 is a perspective view of the tubular fabric covering material;and

Fig. 6 is a view similarto aportion of Fig. 3, illustrating a slightlymodified construction.

The invention as illustrated ina lamp shade construction consists of aunitary frame made up of 'top andbettom annular rings Land --2-rigid1yconnected together by the rods 3, over which is arranged a tubularseamless cover, preferably knit or otherwise formed, so that it issubstantially stretchable, whereby it may be stretched over the frameand, due to its inherent characteristics, draw or contract and maintainitself taut or tighten the frame.

The particular fram illustrated, as before mentioned, consists of topand bottom frame members suitably connected together, one or both of theframe members being shaped to suit but as shown only the bottom framemember, being of channel shape. The bottom frame member 2 as illustratedconsists of a strip [of suitable material, preferably in the form of ametal stri ,'which is provided with spaced flanges 5 and 6. In thedrawing the flanges are shown as extending outwardly, but as will behereinafter described, they might be turned inwardly and the channeledmember might be either at the top or bottom or both, only the bottommember, however, being shown in the form of a channel. As most clearlyshown in Fig. 4 the flange 6 is provided with serrationsproviding prongs1-1, etc., which may be bent down as hereinafter described when thecover is applied to the frame and to secure one end of the cover inplace. In some instances both flanges might be serrated.

The cover III, as shown in Fig. 5, is made in the form of a sea'mlessknit or woventube open at the two ends. At one end, as shown the bottom,the same is hemmed or folded over a securing ring I I, the edge end l2being stitched to the adjacent body of the cover as indicated at l3 sothat thering is held in place on the cover. The ring II is of a size tofit in the channel of the frame member 2, it being possible to springthe same into place, and when so positioned will be held in place whenthe cover is drawn to the interior ofthe shade, as shown in Fig. 4, andat the same time holds the cover edge firmly in place. The cover isdrawn through the shade and up over the frame member I and then the edgedrawn back to the frame member 2 and moved inwardly, wherebyitwill beengaged by theprongs I. If desired, a reinforcingstrip l4 may be securedabout the edge of the cover, although ordinarily this is "not considerednecessary. After the same is positioned, as shown in Fig.- 4, the prongsI may be turned down or bent over as indicated in Fig. 3. After thecover hasbeen applied to the frame, a tape orornamental strip l 5 may beapplied at the top and-likewise a strip H5 at the bottom, as shown inFig. 1. While-I havenot illustrated a constructiomin-whioh.thaflangestaa-framemerm her are turned inwardly instead of outwardly, sucharrangement and application of the cover thereto is obvious from thedisclosures made herein. Likewise, while I have referred to a seamlessknit tubular cover, I wish to include any elastic or semi-elasticmaterial which will be satisfactory.

The construction shown in Fig. 6 is very similar, except in thisinstance the channeled frame member l920 is not provided. with aserrated flange. The cover at the ends of the tube [0, indicated at l8in Fig. 6, is provided with the rings 2| which are secured in place bystitching the ends 22 as indicated at 23. Thi cover is appliedsubstantially as previously described, except that the two rings 2| aresprung into place, thereby retaining the cover on the frame. Tape may beapplied similar to tape l6 shown in Fig. 1.

As was previously mentioned, it is more or less immaterial which ring orframe member is channeled, or whether the flange of the channel extendsinwardly or outwardly, but the preferred construction and arrangementare as shown in the figures of the drawing. The covering being ofseamless, stretchable material in the form of a tube, may be readilyapplied to the frame, and owing to its inherent qualities orcharacteristics, will tend to contract and maintain itself taut on theframe, free from wrinkles or bulges. The

cover may be knit or Woven with an intermediate section of a reduceddiameter like an hour glass, as indicated by the dotted lines in Fig. 5,where it is to be extended over a frame member of less diameter thanthat at the ends, and vice versa, or it may be knit in one, two or moresections. I have not shown in the drawing any support for mounting thecovered frame on a fixture, it being understood that any suitablesupport may be employed, the same being generally attached to the topframe member at a plurality of points, but it may, in some instances, beattached to the lower frame member and be likewise constructed so thatit may be applied to a desired lighting fixture.

Having thus described my invention, it is ob- .vious that variousimmaterial modifications may be made in the same without departing fromthe spirit of my invention; hence I do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described, or uses mentioned.
